Application filed September 12, 1907. Serial No. 392,517.

To all whom it may concern:

Be it known that I, GEORGE E. OBRIEN, a

citizen of the United States, residing at Bufwage computing device and the object of the invention is to rapidly and accurately compnte by mechanical means the entire amount due a workman or employee when the hours of employment and wage er hour are known.-

The invention also re ates to certain details of construction of the device and the wage computing chart or scale forming a part thereof and will be hereinafter described tion and claimed, reference being had to the ac, companying drawings, in which, Figure 1 is a front elevation of the improved wage computing machine. Fig. 2 is an end elevation of the improved wage computin machine. Fig. 3 is a transverse secthrough the improved wage computing Fig. 4 is a transverse section on line b b, Fig. 1, showing the manner of adjustably securing the drum or casin to the supporting brackets. Fig. 5 is an en ar ed section on line 0 c, Fig. 4. Fig. 6 is an en argled fragmentary horizontal sec the im roved wage computing ig. 1. Fig. 7 is an enlarged fragmentary transverse section on line 6 c, Fig. 1. Fig. 8 is an enlar ed fragmentary transverse section on line 1, Fig. 3', through two of the end pieces showing the bearing of the supporting shaft. Fig. 9 is a fragmentary section on line g g, Fig. 6.

Fig. 10 is an enlarged fra mentary detached view of the outer scale w 'ch is mounted on the casing. Fig. 11 is an enlarged fragmentary view of the chart.

In referring to the drawings numerals deslgnate like arts.

This improved device as a base 1, of suitablematerial upon which n right standards are secured by screws 2, or t elike.

Two standardsare preferably employed of similar form, each of which consists of a horizontal lower member 3, through-which the screws 2, are passed to secure the standard to the base; two vertical side members 4, ,in' separated arrangement and a curved top' member 5, extending between and connecting the upper extremities of the side memin detail, like p casing extensions 8 1n the slots 6 of the two I bers. The curved top'members are provided with longitudinal slots 6.

Upon the standards is mounted an outer casing or drum 7, of cylindrical form and ronumbers. Below the slot is placed a scale for indicating the wages due for fractions of an hour at the different'scales.

At the left and vertically below the words Hours over the slot. are arranged the fractions T1- and in a vertical column which indicate respectively a quarter of an hour,- one half of an hour and three quarters of an hour. Extending toward the right in three horizontal rows are (lOClIil8.l-lhdl0&tlflg re- ?ectively the wage per fractions of an hour.

hese decimals are arranged invertical columns and each column is located vertically beneath the proper wage rate per hour of which it indicates the wage for the fraction thereof according to the fractional hour scale placed at the left of the vertical columns.

The casing or drum 7 has its ends closed by circular end pieces 1 1 which are secured therein by screws 12 so as to be easily removable. The end pieces are provided with central circular journal openlngs 13 in which a longitudinal shaft 14 is journaled.

The casing can be regulated to bring the view opening or slot in the best position to be quickly viewed by the eye of the operator by loosening the butterfly nuts 9 and turning the members 5 of the support.

A cylinder 15, slig itly smaller in circumference than the casing is-mounted on the shaft 14 and attached to its periphery is a wage computing chart which consists of ligures in horizontal rows and vertical columns printed upon a suitable sheet of paper 16, or the like.

The horizontal rows of figures are arranged so that they ma be viewed through the slot 10, as the cylin er is revolved, the left hand vided with screw threaded extensions 8, w ich pear above the row of indicating wage per hour This column will be hereafter referred to as the hour indicating column.

To the right of the hour indicating column are columns of figures which each indicate the total wages due for the numbers of hours indicated by the numeral horizontally to the left in the hour computing column and at the rate per hour indicated by the numeral located vertically over the slot 10. Each figure or set of figures exposed through the slot is the product of the number of hours indicated by the numeral at the extreme left of the horizontal row in which the figure or set of figures is located multiplied by the wage' rate per hour indicated by the numeral or numerals at the top of the slot vertically over said figure or set of figures. Thus in Fig. 1, eight dollars and sixty four cents is the product of forty eight hours multi lied by eighteen cents the rate er hour. hese columns will be hereafter esignated as the total wage columns.

For illustration referring to Fi 1 a workman receiving twenty cents per our would for forty eight and three quarters hours work have coming to him nine dollars and sixty cents which will be found exposed through the slot and vertically beneath the twenty cent rate per hour plus fifteen cents which will be found in the horizontal row to the right of the three quarter fraction of an hour and in the vertical column below the twenty cent wage rate per hour. The chart on the cylinder can be easily changed by loosening the screws 12, removing the end piece 1]. and withdrawing the cylinder from the casing. The left projecting end of the shaft is provided with a knurled knob 17 for convenience in turning the cylinder. The scale of the rate per hour and the fractional parts of the hour is printed upon a pa er sheet 18of suitable size and provided wit 1 a slot corresponding to the slot in the drum or easing. Upon the outer surface of the casing is fastened a strip 19 in roximity to the slot 10 which is separated sufficiently from the surface of the casing to provide a groove in which the sheet 18 and a protecting cover 20 of celluloid or similar transparent material is fitted and supported see Fig. 6.

It will be observed by referring to Fig. 1, that the strip 19 does not extend over the slot so that the sheet 18 and its protecting cover can be easily removed or replaced in position.

The great advantage of this device is that given the number of hours worked and the stant y ascertained thereby saving the laborious labor of manually computing the same.

In computing with this device the operator turns the cylinder to ex ose through the slot the number of hours' esired and then follows the slot toward the right with his eye to the figure or set of figures exposed in the slot vertically below the desired rate per hour which is the total amount due for the full hours desired at the required rate per hour.

If the em loyees time includes a fractional part of an hour, the amount due for said fractional part can be ascertained from the table below the slot and easily added mentally by the operator to the told amount due for the full hours to give the entire amount due to the employee.

The purpose in making the strip 18, and the sheet 16, removable is to provlde means for easily changing, reversing or altering the scale and chart when desire I claim as my invention 1. In a device of the class described, a base provided with slots, an outer casing having extensions adjustably fitting in the slots of the base; said casing being also provided with a view opening and a scale of different rates of wages per hour in proximity to said opening and a cylinder within the casing having a wage computing chart with the hours in a column and the wage figures in columns corresponding to the hour column and arranged in line with the proper wage rate of the scale on the casing.
